Occupy Wall Street protesters who defied a deadline to remove their weeks-old encampment on the Los Angeles City Hall lawn stood their ground Tuesday as they faced uncertainty over when or if police would push them out of the park — and if an eviction could happen without the kind of violence that has engulfed the removal of protest sites in other cities.

Protesters in the nation's second largest city have turned to the federal courts to keep officers away after disobeying a city-imposed 12:01 a.m. deadline Monday to take down their camp. They argue that the City Council passed a resolution in support of the movement and that the city's mayor and police did not have the authority to evict them.

The chances that protesters will get an injunction appear slim, constitutional experts say.

Meanwhile, city officials said they will only move in on the camp when conditions are safest not just for protesters and officers but also the roughly 100 homeless people who had joined the encampment.
